Bento (TPG), the male is a WF mosaic RT, possible piebald (how would I check piebald?)-His father is 100% het for leucistic - Proven out From a piebald producing family-His mother is RT, 50% het for leucistichow do I calculate Bentos %leu? would he be 75% het until proven out?

btw, he has now fathered a joey with a WF Blonde 100% het for leucistic. would the joey be considered 87.5% het?

However the brother to Bento if he has thrown a Leu.... and if his mother and father are the same to both Bento and the brother... then this would mean that Bento has a Possibility of being a 66% Leu Het because the parents would be proven 100% Leu Hets.

PS: A pairing with a Possible 50% Leu Het to a WFB/100% Leu het will give you offspring anywhere between Possible 50% to Possible 66% Leu Hets. Myself, I call these offspring only Possible 50% until a leu has been produced and only then do I call them Possible 66% Het for Leu. 50% of the babies produced should also be White Face Blonds on average.
